Mix Firmata code with my arduino code to get digital pins read write in max

Hi there!!

I currently have a piece of code from Tod Kurt, that works as an i2c to serial adapter. It lets me send messages to BlinkM led lights via the serial object in max msp.

I was wondering here if anyone could add on support for the digital pins in max msp onto his code so as that I can attach an IR sensor and have the max patch read from it.

I have no coding experience so this is why I need your help.

Or does anyone have a solution for my problem that is. To have the i2c serial communication working, as well as getting digital pins read in and out from Max Msp, so as to read a sensor into max msp.

many thanks.
